I'm looking for some expert help on the subject of how to prepare images for ebooks, for the essential ebook formats, reading systems and devices. I thought that I could capture two pigeons with one bean if I not only gathered this information, but shared it with the epublishing community.

Please take a glance at this web page -- down on the bottom half of the page -- and you'll see the beginnings of some tables where much information is needed.

I think that JSWof's good advice (which I will add to this project's web page) has something to do with the aspect ratio. I couldn't get an EPUB ebook cover image to show up using Stanza desktop, and then I adjusted the aspect ratio, making the image less wide, and then it appeared perfectly.

A test is always needed to see if the image shows up, if the image is still sharp, if it's in the right location, and so on.

This is one of the main points of my information-gathering project: to find "the right specs" so that ebook publishers can produce one -- only one ! -- version of the ebook that fit all the various reading systems (or: all the significant ones), and to avoid the trouble and chaos of needing to produce many different versions of the same ebook.
